Anisotropic photonic time interfaces via isotropic spacetime modulations
Andrew M. Naylor, Victor Pacheco-Peña
The engineering of the optical properties of materials in space and time is opening further directions and possibilities to control wave propagation in four dimensions (x,y,z,t). A…
Mirrors without spatial boundaries
J. Enrique Vázquez-Lozano, Victor Pacheco-Peña, Iñigo Liberal
Mirrors are one of the most elementary and ubiquitous components of optical systems. They use a sharp refractive index contrast to provide the basic capability of reflecting light.…
Emulating photonic time interfaces via smooth temporal transitions
Mariya Antyufeyeva, Victor Pacheco-Peña
The introduction of time as an additional degree of freedom to control wave-matter interactions have opened new avenues to fully control wave propagation in four dimensions (x,y,z,…
Spatiotemporal cascading of dielectric waveguides
Victor Pacheco-Peña, Nader Engheta
Photonic time interfaces, as the temporal analogue of spatial interfaces between two media, consist of a rapid change of the electromagnetic properties of a material (such as permi…
Temporal chirp, temporal lensing and temporal routing via space-time interfaces
Victor Pacheco-Peña, Mathias Fink, Nader Engheta
A time interface (a rapid change of the constitutive parameters of a material in time), applied within an unbounded medium where a wave travels, can enable frequency conversion, an…
Perfect Splitting in Rectangular Waveguide Junctions for Analogue Computing
William Rogers, Christian Johnson-Richards, Alex Yakovlev +1
It has been recently shown how computing operations such as high-speed switching, routing, and solving partial differential equations can be performed by exploiting perfect splitti…
Plasmonic sensing using Babinet's principle
Joseph Arnold Riley, Michal Horák, Vlastimil Křápek +2
Developing methods to sense local variations in nearby materials, such as their refractive index and thickness, is important in different fields including chemistry and biomedical…
Holding and amplifying electromagnetic waves with temporal non-Foster metastructures
Victor Pacheco-Peña, Yasaman Kiasat, Diego M. Solís +2
We introduce a mechanism that can both hold and amplify electromagnetic waves by rapidly changing the permittivity of the medium during the wave travel from a positive to a dispers…
Neural network design of multilayer metamaterial for temporal differentiation
Tony Knightley, Alex Yakovlev, Victor Pacheco-Peña
Controlling wave-matter interactions with metamaterials (MTMs) for the calculation of mathematical operations has become an important paradigm for analogue computing given their ab…
Quantum antireflection temporal coatings: quantum state frequency shifting and inhibited thermal noise amplification
Iñigo Liberal, J. Enrique Vázquez-Lozano, Victor Pacheco-Peña
We investigate the quantum optical response of antireflection temporal coatings, i.e., matching temporal layers that suppress the generation of backward waves in temporal boundarie…
Temporal metamaterials with gain and loss
Victor Pacheco-Peña, Nader Engheta
Manipulation of wave-matter interactions in systems with loss and gain have opened new mechanisms to control wave propagation at will. Metamaterials and metasurfaces having spatial…
Spatiotemporal Isotropic-to-Anisotropic Meta-Atoms
Victor Pacheco-Peña, Nader Engheta
Metamaterials and metasurfaces are designed by periodically arranged subwavelength geometries, allowing a tailored manipulation of the electromagnetic response of matter. Here, we…
Temporal Brewster angle
Victor Pacheco-Peña, Nader Engheta
Controlling amplitude, phase and polarization of electromagnetic waves is key for a full manipulation of wave-matter interactions. The Brewster angle is one of the important featur…
